MINING PLAN <br />Stockpile Protective Seed Mixture <br />When soil or overburden stockpiles are seeded they will be planted with the following <br />mixture. This mixture is based on a broadcast seeding of the stockpile. In the event the stockpile is <br />drill seeded (not recommended for 3:1 or steeper slopes due to the hazard of operating equipment on <br />steep slopes) then the seeding rate will be divided in half. <br />Seed Mix for Stockpile Protection <br />(Broadcast seed rate -divide by 2 if drilled) <br />Species Pounds PLS/acre Live Seeds per sq ft <br />Blue Grama 2 32 <br />Western Wheatgrass 5 14.5 <br />Streambank Wheatgrass 4 14.5 <br />Totals 11 61 <br />1. Time of seeding: Whenever it is determined that seeding is necessary as dictated by <br />the expected duration of stockpiling. <br />2. Post seeding treatment: If broadcast, drag the surface to help bury the seed unless <br />the surface is very loose and has lots of crevices at the time of seeding. <br />3. Post planting management: Follow weed control requirements for stockpiles, but <br />avoid using herbicides that would kill the grasses in the protective seeding (i.e. do not <br />use RoundUp® or other generalized herbicides that kill everything). <br />Coal Creek Sand Resource Amendment 3 (2005) - M-1988-044 Exhibit D Page 35 <br />
